Modern man has an obsession with meat.
As more and more people migrate to cities, their meat consumption increases. Harvesting animals to cater to the demand has had massive repercussions to the environment. Whether it's global warming from increasing atmospheric levels of methane from cattle flatulence, or hormones (such as BGH) used to boost yields that ends up in our bloodstreams, or the calamities of monoculture to grow the feed required to fuel demand, the impact is more than we can imagine.
Even Google has tinkered with the production of synthetic meat in order to find a more environmentally friendly way to solve the perceived shortfall. And, on the other end of the spectrum, Kobe beef has fostered an even greater, gourmet obsession with cattle becoming the bovine version of foie gras.
What will happen when meat becomes less obtainable? Will it become the new caviar? Will there be a black market wherein real meat becomes a collector's item? Will new sources of clandestine meat take us to darker pastures (such as the recent horse meat scandal in Europe). Is there any meat that will be off-limits in the future? And, what if meat becomes outlawed altogether, what then?
Imagine a world in which meat becomes highly politicised, highly desirable, and increasingly taboo.
